Grady, Cheadle Hulme, to said Muschamp Application April 16, 1953, Serial No. 349,218 3 Claims. (Cl. 221-22) The present invention relates to improvements in or relating to a core delivery device for cop winding machines, and in particular to automatic cop winding machines in which cores are carried successively into a winding station between a winding spindle and its tail stock.

Winding machines of this type require a magazine for the cores so that there is always a core ready for presentation to the winding station as soon as the winding of the preceding cop has been completed.

The loading of the magazine with cores must always take a certain length of time, and it is an object of the present invention to provide a magazine which can be quickly loaded with a very simple operation.

According to the present invention, a core delivery device comprises a slowly rotating magazine adapted to deliver one core in each revolution of the magazine to a core holder and means for disconnecting the drive to the magazine when a core is located in the holder.

In the accompanying drawings:

Figure 1 is a perspective view showing one example of a core delivery device made in accordance with the present invention;

Figure 2 is a fragmentary longitudinal section showing the driving end of the magazine and the drive therefor, as

shown in Figure 1;

Figure 3 is an end view of the magazine;

Figure 4 shows an alternative construction of feeler mechanism;

Figure 5 is a rear perspective view showing another example of a core delivery device according to the invention;

A Figure 6 is a sectional side elevation;

Figure 7 is a sectional end view of the magazine.

As shown in Figures 1 to 3, the magazine of the device comprises a stationary outer cylinder 10 open at one end and supported from a suitably located rail 11 by means of a bracket 12, the axis of the cylinder being slightly inclined upwardly towards the open end. The outer cylinder 10 is formed at onevside with a delivery slot 13, slightly above the level of the axis, of tapered shape corresponding roughly to that of the core. side of the cylinder is a chute 14 inclined oppositely to the axis of the cylinder, the upper end of the chute being attached to an extension 15 of a base flange for the cylinder. concentrically within the cylinder 10 and closely fitting therein is rotatably mounted an inner cylinder 16, carried by a spindle 17 journalled in a boss 18 formed on the bracket 12. In the side of the inner cylinder is a slot 19 also of tapered shape corresponding roughly to that of the core but so formed as to provide an inwardly projecting and inclined lip 20 wide enough to support only one core at a time. On the outer end of the spindle 17 is secured an arm 21 which is set at an angle of about 45 degrees behind the position of the lip 20 (see Figure 3).

Mounted on the rail 11 behind the magazine is a bracket 22 having a boss 23 carrying a driving spindle 24, co-

axial with the spindle 17 of the rotary cylinder. Such Secured to one 2,834,509 Patented May 13, 1958 spindle 24 is movable axially in its boss and on its end adjacent the magazine is secured a pulley 25 having a driving pin 26 projecting from its front face and adapted to be engaged with the arm 21 to impart rotation to the spindle 17 and cylinder 16. The hub of the pulley 25 is hollow to form a housing for a spring 27 while the end of the hub is shaped to provide a face cam 28. The pulley 2:3 is adapted to be driven by a belt 29 which is positioned above and pressed on to the top of the pulley by a grooved pulley 30 carried by an arm 31 pivotally mounted in a lug 32 carried by the bracket 22. Said bracket has a further lug 33 carrying a pivot pin 34 for a U-shaped lever, the shorter limb 35 of which has a cam follower 36 and the longer limb 3'7 of which has a slot 38 at its end, to cooperate with fecler mechanism described below.

The head of the winding machine is shown in outline at 39 with its spindle centres 40 and 41. On the side of the head are brackets 42, 43 carrying feeler mechanism and consisting of a bar 44 slidably mounted in the bracket 42 and having at its rear end a pin 45 engaged with the slot 38 aforesaid. Pivotally attached to the bracket 43 is a stop lever one end 46 of which is downwardly bent and projects just below the lower end of the chute, and the other end 47 of which engages a step in the adjacent end of sliding bar 44. The stop lever is shown tilted by the engagement with the head of a core 48 which, having slid down the chute is positioned in a V-shaped cradle 49 of a loading arm arbor 51 fixed in and projecting from the winding head. The stop lever is so balanced that when the end 46 is not engaged with a core, the other end 47 falls to a horizontal position just below the adjacent end of the bar 44. On the end of the arbor is secured a stop 52 which determines the lengthwise location of the core 48 in the cradle 49. The loading arm is adapted to be pivoted by means of a link 53 and other mechanism not shown, to

present the core to the winding centres 40, 41 when required.

in operation, the belt 29 which may drive other magazines for a row of winding heads is driven at a slow speed in the direction of the arrow A so that the pulley 25' is driven at about 3 revolutions a minute. Cores 48 are loaded loosely, head first, into the cylinder 16 so that it is a quick and easy matter for an operative to keep the magazine filled for several winding spindles by refilling them at convenient moments while watching and occasionally attending to the spindles. Considering one winding head and assuming that there is no core located in the holder 49, the operation of the device is as follows:

The pulley 25 is advanced by the spring 27 to a position in which its driving pin 26 will engage the arm 21. Before reaching such position of engagement, the nose of the cam 23 engages the follower 36 rocking the arms 35 and 37 and causing the bar 44 to be pushed towards the end 47 of the stop lever. Such end 47 is however below the end of the bar and therefore no resistance is offered to sliding movement. The cylinder 16 is therefore caused to turn and one core will be picked up by the lip 2d and held positioned in the slot 19 (see Figure 3) while resting against the inner face of the outer cylinder 16. When the core reaches the slot 13 in the cylinder it? it falls out on to the chute, the pulley continuing to rotate the cylinder 16 until it again reaches approximately the position shown in Figure 3. The core 43 slides down the chute into the holder 49, its end coming to rest against the stop 52 while its head engages and depresses the end 46 of stop lever which is free to tilt as the bar 44 has moved back due to further rotation of the cam. 28 before the core has reached the outlet slot 13.

When the pulley starts its next revolution there will be a core in the holder 49, consequently the bar 44 will 56 pivotally mounted on an be held by the end 47 of the stop lever from moving as the nose of the cam engages the follower 36 and the pulley with its spindle will be pushed axially away from he. magazine so. that its. driving pin 26 passes behind the arm. 21 and noelfective rotation is given to the cylinder 16 T e Pulley moves back. again on its spindle as soon as the cam nose permits such. movement. Subsequent rotation of the pulley 25- therefore continues without imparting rotation to the cylinder 16 so'long as. there is a core located in the holder. 49. As soon however as the core has been; loaded from the holder, the drive operates to rotate the cylinder and deliver a new core, to thev holder. The. speed. of. drive. of the pulley is, so'proportioned that. several core discharging move.- ments. could take place between intervals of movement of the, holder for; feeding. a core. to the winding centres and thus ensures the holder being loaded even though the magazine. may turn but fail once or twice to.- deliver a core.

In the modification shown in, Figure 4, the bar 44 is downwardly turned, to 54 to engage direct with theend of a core, shown in the position in which it would be located by the holder. The construction operates in exactly the same. way as that shown in Figure 1 except that sliding movement. of the. bar 44 is directly checked by the core instead. of, by an interposed stop lever but such checked sliding movement has. the same result of sliding the pulley away toprevent effective. driving engagement. of the pin.26-. with the arm 21.

In the construction shown in. Figures 5, 6 and 7, a single rotatable cylinder 55 is provided, rotatably mounted. on an upwardly tilted stud. 56 fixed in a bracket. 57 secured to the rail 11, the hub 58a of the cylinder abutting against the boss of the bracket. On the. end of the stud. is a fixed retaining plate 59. which prevents axial movement of the cylinder. The cylinder has an-end stud 60 by which it may be rotated, and is. formed with aside aperture 61. over whichis pivotally mounted a. flap 62 to which. is. attached an actuating arm 63 overhanging the. lower end of the cylinder. A spring 64 is provided to close the flap.

Rotatably and slidably mounted on the hub 58 of the cylinder is. a driving member consisting of a worm: wheel 65 carrying a driving pin- '66 complementary to the stud 6,0 of the. cylinder, and a face cam 67.. Behind the cam 67 is a. spring 68. The bracket. 57 has anextension. which carries. apin69 on which ispiyotally mounted a, U-shapedlever having a. short arm. 70. carrying v a cam. follower 71., complementary to the cam 67 anda longer arm 72 to the lower endof which is attached one end of a link, 73. Alight. spring 94 on the pin 69 urgesthe follower. into contact with its cam. The bracket 57' has a further extension carrying a trip stud 74. complementary to the arm 63 of the shutter 62. Attaehedto the rail'll is a.further bracket 75 carrying a shaft 76 on which is a worm 77 complementary to the worm wheel 65. Such shaft. is. intended to extend the length of several magazines for a bank of Winding spindles and therefore its driving. means, which will be atone end,.is not shown. Also on the shaft 76 is apulley 78 for an inclined: conveyor belt 79. forming the. bottom of a chute 80 which will be secured in they position.shown to the side. of the winding head (not shown). In the side. of thewinding head (not shown) is also a pin 81 on,which is pivotally mounted a stop lever 82 while theend.v of the, link 73 has a. slot 83 slidably engaged with the pin- 81 and centrally positioned by collars 84 on a the pin and between upturned sides85-of a spade-likeend of the lever 82, the. extreme end of. which is. adapted to be engaged; by ablock. 86 fixed to the side of. the link 73. A core,48.is shown-in aholder 49- and located against a. stop 52 similar to those shown in Figures 1 to 3.

In operation, the shaft 76 is rotated at a speed which could revolve the cylinder 55 at about 3 revolutions a "4 minute. Cores 48 are loaded loosely into the cylinder head first as for the cylinder of Figure 1.

Assuming there is no core. in the holder 49, when the peak of the cam 67 engages the follower 71 the arms 70 and 72 can swing freely as the block 86 moves above and clear of the end of the stop lever 82. The worm wheel 65 is therefore held in its advanced position by the spring 68- so that its driving stud 66 engages the stud 60 on the cylinder to rotate the'same. The aperture in the side of the cylinder,v being. provided. with a lip 20' similar to that. shown in; Figure 3 picks up one core and carries it until the shutter 62 is tripped open by the trip stud 74 engaging thev arm 63,. whereupon the core falls onto the conveyor belt 79' which carries it down positively into the holder, th.e:.h.cad of: thecore finally falling onto and tipping the stop lever 82. In the meanwhile the cam has turned also so that its nose no longer engages the follower and the link 73 has. returned to. the position shown in. Figure. 5 so that the stop lever 82 is also free. to be. tilted. into; the. position shown.

On. the next. and. any subsequent rotation of the worm wheel, whiletherev is a core 48: intthe holder, the cam nose cannot slide. the link 73 because the block 86 engages. the. end 86 of the stop lever 82. Consequently the cam is forced by the follower to slide back against the spring 68 so that the drivingpin 66 passes: the stud 60. as. shown in Figure 6 and no. rotation. is transmitted. to the cylinder.

In each of the examples. above described: thev speed of rotation of the cylinder. is so. slow that even if the. holder has. been moved. to.the. centresat the instant before the cam starts. to acton itsfollower, the core will not be. delivered; to. the chute. before the holder will have been. returned. toits .normalpositiom ready to receive the same.
